However, when it comes United's current on-pitch problems, none of those issues are as significant as their struggles in front of goal.

We're not talking about their basic finishing or their chance creation.

No, it's worse than that. As the table below shows, Jose Mourinho's side have missed more 'big chances' this season than any other Premier League side.

So, what counts as a 'big chance'? Glad you asked. Opta keep records of them. Here is their definition:

The big chance category is when you expect the player to score, regardless if it is assisted or not. So for example, a defender could pass the ball to the striker, he goes through on goal and blazes over, that would be a big chance missed.

Further to this, a big chance will always be a shot. It's a qualifier for a shot, so if someone goes clear on goal and technically it's a good chance but they don't get a shot away then it doesn't get a big chance qualifier (as there was no shot).

In short, if you miss a sitter, Opta make note of it.

And it turns out United have missed a huge FOURTEEN of these big opportunities - three more than anyone else:

Some United fans will no doubt claim they have only missed more because they are creating more than anyone else.
